​“My Cousin Vinny” star ​Marisa Tomei’s mom and dad “Imagine” a life without next-door neighbor Sean Lennon’s tree ​encroaching on their Greenwich Village property would be much ​more peaceful.

​So ​Gary and Addie Tomei are suing John and Yoko’s ​kid for $10 million, claiming he’s letting a rotting ​ailanthus invade their stately townhouse at 155 W. 13th St.

The ​Brooklyn-born actress’ folks say the roots of a 24-inch-diameter, 60-foot-tall tree in​ fellow native New Yorker Lennon’s front yard at 153 W. 13th St. have cracked the Tomeis’ stoop, broken their iron railings, compromised the basement wall and even crept into their basement floor.

In a September 2014 letter to the Beatle scion, the Tomeis’ attorneys say Lennon has refused to remedy the problem even though his own arborist and mason confirmed the hazardous condition.

Better known as a “tree of heaven,” the offending vegetation is ​actually ​an invasive species ​originally ​from China. The suit says the tree is 50 years old, but diseased and partially hollow.

The Tomeis want the tree cut down plus $10 million. Lennon bought the three-story, 4,000-square-foot home for $9.5 million in 2008.

It’s currently under construction.

The Tomeis also rent out a duplex in their 19th-century brownstone for $9,000 a month.
